REGISTER BLOCK,

Application filed June 29,1922; Serial No. 571,763.

To all whom it may concern:

Be it known that I, Form WALLICK, a

citizen of the United States, residing at Peru, in the county of Miamiand State of Indiana, have invented new and useful Improvements inRegister Blocks, of which the following is a specification.

My invention pertains toregister blocks, and relates particularly toregister blocks for'use uponthe platen of a platen printing press.

It is an object of my invention to provide a register block of a simpleand rugged construction which will permit of a sheet to be printed beingplaced in an accurate registeredposition, andwhich will, of itself,maintain the sheet in such registered position. It is another object ofmy invention to provide a register block which will prevent reboundingof the sheet when the latter is 'presentedflforcibly, to it, as for myinvention will appear from the following description and the claims.annexed thereto. r

I have shown, by way of example, in the accompanying drawing, anddescribed in the following specification, two forms of register blockconstructed in accordance with my invention. 1 wish it understood,however, that the invention may be embodied in other forms, and thatchanges may be made in the forms described and shown, without exceedingthe scope thereof, as defined in the appended claims.

In the drawings: i

Fig. 1 is a partial perspective view showing a printing press platenhaving register blocks constructed in accordance with my inventionapplied thereto;

Fig. 2 is an enlarged plan of one of the register blocks shown in Fig.1;

Fig. 3 is a section on the line III-J11 of Fig. 2;

Fig. 4 is a plan of a modified form of my register block; and

Fig. 5 is a section on the line V-V of Fig. 4.

My invention is particularly advantageous where large quantities ofprinting of the samekind are to be turned out. It is here illustratedas' used in connection with .the printing of a large number of envelopesof approximately the same size.

Referring now to Figures 1 to 3 of the drawing, 10 designates the platenof a Gordon press, having extending across the :center thereof,a tympanstrip 11, secured in place by the usual bails 12. This strip is ofsufficient width to accommodate the part of the envelope which is to beprinted upon, and leaves bare the surface of the platen ateach sidethereof. Two register tympan strip 11. Each block includes a member13having formed therein a lengthwise-extending elongated slot 14, throughwhich extends a cap-screw15 threaded into a suitable hole in the platenface. From the front of the member 13 extends forwardly a tongue 17,formed so as to produce between itself and the platen facea' slot 18into which the edge of the sheet or envelope may be fed, said slotterminatingin a reg ister shoulder 16. The front end of the tongue isbevelled below, as indicated at19, to facilitate theentry of the sheetor envelope therebeneath. A tapered hole is blocks are used, one at eachside of'the formed in the tongue 17, which hole receives a ball 20 insuch manner that the 'ball projects beyond the lower face of the tongue,and engages the face of the platen. A leaf spring 21 yieldingly pressesthe ball 20 against the face of-the platen.

The pressure of the springs balls 20 is such that while no harmfulresistance is opposed by the balls to the passage of the sheets orenvelopes therebeneath, in being fed to register against the shoulders16, yet the balls 20 will prevent the rebounding which sometimes takesplace when the sheets or envelopes are fed very rapidly, as when fed byautomatic machinery. This is an important advantage. Another advantagelies in the fact that the register blocks will retain the sheet orenvelope securely in position during the first part of the movement ofthe platen towards printing position, before it is seized by the regularplaten. grippers. Further advantages lie in the ruggedness ofconstruction of the register blocks, their easy attachment, and theirlack of liability to get out of Order- By reason of the slot and screwcon- 21 upon the v motion with the platen, endwise adjust ment of theblock, to accurate register 3P0Sltion, is easily obtained.

A modified form of my improved register block is shown in Figures 4 and5. In this form the slot 14 of the member 13 is 'enlarged at its upperpart, to permit countersinking of the head of the screw 15. In thisinstance, also, the tongue 17 is made solid, and the ball 20 made toengage .against its lower face, :being mounted in a recess 22 formed inthe platen 10, and pressed upwardly by a spring 21.

- Having thus fully described any said invention, what I claim as new,and desire to secure by Letters Patent, is:

it. The combination with a platen member, of :a register block, meansfor securing the same to the platen, said block having a rigid ffingerspaced from :the platen, and :means associated with the finger andplaten for :holding a sheet after being placed against the block. I

2. The combination with a printing-press :platen of a register blockhaving an elongated slot, ascrew disposed in said slot and entering saidplaten, whereby said block is .adjnstably secured 'to said platen, and aresilient sheet-Vengaging member disposed between said platen and saidblock.

3. The combination with a platen member of a register block having aprojecting guiding tongue :member said block having an elongated slot, ascrew disposed in said slot and entering said platen member, and aresilient device associated with one member and engaging the othermember.

4. T he combination with a printing press platen of a register blockformed with an elongated slot and with an integral ex-tending guidingtongue member, a screw disposed insaid slot and enteringsaid platen,whereby said block is adj ustably secured to said platen and meansassociated with the tongue and platen for retaining a sheet in positionagainst the block after the same has been presented thereto.

5. The combination with a platen member of a register block formed withan elongated slot and with an extending guiding tongue member, a screwdisposed in said slot and entering said platen member, and a resilientdevice-associated with one member and engaging the other member.

6. A register device including a member for attachment to a platen, atongue extending forward from said member, ball for operation betweensaid tongue and the platen, and spring means for acting on said ball.

7. A register device including a slotted member, :a tongue extendingforward from said member so as to form a register a butment at the basethereof, ascrew forentering the slot of said member and securing to aplaten, a ball for operation between said tongue and the platen, andspring means for acting on said ball.

8. The combination with :a .printi ng-press platen of a register deviceincluding a :number ha'vingan elongated slot tl'rerein, a screw in saidslot and entering :said platen, a tongue extending forward firom'saidmember :so :as to form a register abutment at the base thereof, a balldisposed between said tongue and said platen, and a spring operating onsaid ball.

'9. The combination with a printin press platen, of .a register blockadjust-a 'ly secu-red thereto and having a register shoulder and a rigidlongitudinally projecting i'gui'ding ffin'ger spaced from the platen,and

spring actuatedmea ns opera'tin g b etwe'e'n the tongue and :platen forretaining sheet against sardrslironlder after thesalne has beenpresented thereto.
